PAPER-BOX MACHINE.-

SLPEGIFICATION forming part of Letters iEatent No. 539,80 3, dated May28, 1895.

Application filed July 16, 1 894.

To all whom it may concern:

Be it known that I, CHAUNOEY W. GAY, a citizen of the United States,residing at West Springfield, in the county of I-Iampden and 5 State ofMassachusetts, have invented new and useful Improvements in Paper-Box Machines, of which the following is a specification.

The object of this invention is to produce a machine for making paperboxes of substantially the same form as those shown and described asmade in the machine for which Letters Patent of the United States weregranted to meMay 8, 1894, No. l9,53l,which r5 machine of the presentinvention, while not being entirely automatic in all respects, is ofcomparatively simple and inexpensive construotion, and capable ofperforming the bending and setting operations upon the side and endflaps and stay sections with the utmost efficiency.

' In using this machine, the scored blank from which the box is to bemade has its flaps, which constitute the opposite sides of the box,

bent up by hand, and then introduced into the machine, which on beingthen set in motion gums the blankat one end, turns in the stay sectionsat each end, and bends the corresponding end flap at right angles to thepart c of the blank which constitutes the bottom and causes the adhesionand setting of the end section to, and upon, the inturned stay sections.The-box is then, by hand, withdrawn and turned end for end and themachine on 5 being again set in. motion repeats the aforementionedoperations.

Another object of the invention is to so construct the machine that theoperative devices may be adjusted and adapted to boxes of dif- 0 ferentdimensions,'and the invention consists in constructions and combinationsof parts, all substantially as will hereinafter fully appear and be setforth in the claims.

Reference is to be had to the accompany- 5 ing drawings, in which thepresent improvements are illustrated, and in which Figure 1 is asectional elevation showing all of the principal operating parts of themachine. Fig. 2 is a plan view of the machine with some of the moreunimportant upper parts of the machine brokenaway for clearer Serial No.5 1 7,6 71. (No model.)

Fig. 11 is a perspective view of the completed paperboard boxas seen looking into it. a perspective view of a part of the automaticunclutching mechanism, which insures the stopping of the machine afterone end-flap and stay-section inturning and setting opera-. tion. Fig.13 is a plan view of the mechan- 85 ism shown in Fig. 12.

'Similarcharacters of reference indicate corresponding parts in all ofthe views.

Reference-is first directed to the drawings in which the box-blank isvariously illustrated, 0 and generally indicated by the letter, 00. Ofthis blank, the middle portion, 00 is to be termed the bottom section,the portions, 00 m the end-flaps, the portions, 50 as, the side flapsand the portions, 00 .70 at the ends of the end 5 flaps, the staysections.

The dotted lines in Fig. 9 represent the scoring, or linesof bending. Inthe making of the box after the side flaps have been bent up at rightangles to the bottom section, the roo stay-sections are inturned intoplanes at right angles to the side flaps, and then the gummed Fig. 1.2.is

.the box which is to be produced.

end-flaps are turned in upon and united to the stay-sections.

In the drawings, A represents the bed or tableof the machine which is inthe form of a massive bar or block extended in the manner of across-girder between, and bolted to, the side standards which constitutethe supporting legs, a, a, and uprights, a ,a'". At the front edge ofthis bed, A, are supported two forwardly projected metallic blocks, orthick plates, or castings, B, with plane level tops, 20, and with theopposite outer perpendicular faces, 22. The separation of said oppositeouter faces is to be the same as the width of These blocks, B, whichmaybe termed the blankrests are the parts on and against which thebox-blank is presented and supported and with which co-operate theinturning devices, G, for the stay-sectiot1s,0c and the inturningdevices, D, for the end flap, and which withstand the pressure of thefollower, G, which very forcibly presses and sets the so-inturnedportions of the blank.

The bed, A, has at its front face the large, deep,longitudinalgroove,24,and near 1 hebottom the forwardly standing ledge, 25. Theblank-rests, B, B, are connected, as a matter of preference andadvantage, with the supports, C C for the stay-section inturntngdevices. Said rests, B, have angular or L-shaped lugs or projectionsformed on or secured thereto. The member, 27, of each angular projectionof the rest, B, extends at and beyond the rear edge of the block, B, asseen in Figs. 1, 2 5, 6, 7, and 8, while the other member, 31, of theangular projection has its position alongside the outer face, 22, ofrest, B, and is separated from such face by a distance somewhat greaterthan the thickness of the card-board from which the blanks are formed.The support, 0 is securely screwed or fitted to the member, 31, of theangular projection and as seen in Fig. 4 has the elevated part, orriser, 26. This space,t'or the introduction of the blank,between theface, 22, of rest, 15, and the proximate side of the support, and part,31, is clearlyshown at. y, in Figs. 2 3, 5, (i, 7, and 3. The bed hasthe horizontal slots, 29, 29, through which the said bolts pass, all sothat by said bolts and the nuts, 30, therefor, the rests, l3, andsupports, C", may be rigidly confined in any desired separatedadjustment upon the so-slotled bed. The aforesaid part, 27, fits in thelongitudinal groove, 24, in the front of the bed, A. The lower edges ofthe rests, B, may also have bearings upon the tops of the aforementionedledge, 25.

The combined rests, B, B, and supports, C C for the stay-sectioninturning devices are engaged by a right-and-let'thand screw, 32,suitably journaled and constrained against endwise movement and providedwith the crank-handle, or other adequate means for causing its rotation,through means ofwhich, when the nuts are loosened, to adjust to a nicetythe said parts, 13 and G which move as one part. Now, in each of theaforesaid risers, 26, are formed the transverse oblique way, 33, inwhich is fitted the slide, 0, which constitutes the stay-sectioninturning device, and the way, 34, extending fore-and-aftand deeper thanthe way, 33, in which slides the bar, 35, which carries the stud, 36,which impingesin the cam-slot, 37,0f the stayintnrner so that, duly, theproper transverse movements may beimparted to the sliding device, O.

The actuating motion is imparted to the bar, 35, by means follows: Thecam,40, on the main shaft, F, together with the thrustrod, 42, andcorresponding springs, 43, impart the rocking rec'iprocatory movement tothe arm, 44, of the rock-shaft, 45; and the rocking movement of suchshaft, through its duplicated lever-arms,46, which are connected to thehorizontal rod, 47, impart a bodily reciprocatory movement to said rod,which, being in engagement with the upturned perforated, or slottedmembers, 48, of the bars, 35, drive the latter. turned members of theoperating bars, 35, and the rod, 47, is a loose sliding one so that anyrequired adjustments of the parts, C carrying said operating bars, 35,will be permitted and insured without any attention to this connection.

The device, D, which turns inwardly and rearwardly the end-flap,isconstructed in the form of a pusher block, or plate, carried by theintermediately pivoted lever, 50, the pivotal support, 52, for thislever being in the bracket, 53, which is bolted upon the stationarycross-bar, H, which extends horizontally across the front of the machinebetween and supported by the uprights, a ,a and above the rests, B, B,andwith its rear vertical face in a plane very slightly in advance ofthe faces, 21, of said rests, B. The said intermediatel y pivoted lever,50, has its upper arm in connection with the thrust-rod, 54, the roller55, of which isin operative engagement with the cam, 56, of the mainshaft, F.

The spring, 57, is operatively applied to in-- sure the retractilemovement of the parts as the cam recedes, all as common in this class ofmachinery.

J J represent the gummers. These have a reciproeatory movementhorizontally foreand-at't to gum the end flap near the marginal portionsthereof which are to be brought against and united to the stay sections,00 00 (See Sheet 5.) These gummers have their projection forwardly, togum, in their paths of movement which are just above the rests, B, B,and their gumming impact is against the aforesaid bar, H, though ofcourse directly against the interposed end flap, ad, which, as clearlyseen in Fig. 6, lies against the rear face of this bar up to the gages,60, 60.

The gummers, J, J, consist of suitably faced gummer bodies which aresecured, with their vertical gumming faces forwardly presented, upon thehorizontal bar, 63, which is carried The engagement between the up-- IOLat the forward end of the shaft, 64, which latter is constrained for itsfore-and-aft movements in ways therefor of the guide support, 65. Theshaft, 64, receives its reciprocatory movement by being linked tothelever, 66, of the rock-shaft, 67, which shaft receives its rockingmovement by having its arm, 68, connected to the thrust-rod, 69, theroller, 70, of which is impinged upon by the cam, 72. In conjunctionwith this cam the retracting spring, 73, is operatively applied for themanifest purpose. The aforesaid gummer-supporting-bar, 63, islongitudinally slotted, as seen at 75, whereby, through means of thebolts,76, the gummers may be adjustably confined in any proper degree ofseparation.

The gummers are gum med by means as follows: The gum-box, M, with thegum-box-roll, 71, is mounted above the paths of movement of the gummers;and just forward of the ends of the gum-box are the two oppositestandards, 77, 77, having the slots, 78, which are vertical as to thegreater portion of their lengths, with, however, the rearwardly curvedupper terminals seen at 79, Figs. 1 and 4. The gudgeons of the bodilyreciprocatory gum rollf, extend through said slots, 78, and outside ofthe said standards, they receive connection with the slotted arms, 81,which extend forwardly from the rock-shaft, 84. This rock-shaftisoperated by cam, 85, and spring, 87, through the thrust-rod, 91, andradial arm, 93, of the said rock-shaft, 84. As the arms, 81, are swung,the gum-roil,f, moves, as it is constrained to do by the slottedstandards, vertically over the faces of the then properly positionedgummers, J, and then rearwardly to contact against the gum'box-roll, 71.The aforesaid bar, H, is surrounded by the tube, or envelope, (1, offlexible material, such, for instance, as one constituted in part ofcanvas or other'textile material, as seen at 80, and in part of an extrathickness of rubber as seen at 82, the one edge, 83, of which rubber,thickness is horizontal and longitudinally along the inner face of thebar, H, between its upper and lower edges, as seen in Fig. 6,particularly, The object of this band, or envelope, cl, sur

rounding the bar, H, is to provide at the rear face of the said impactpart, H, an even and proniinentlayeror thickness which is to reach upjust as highas the upper edge of the end ,fiap so that when thegummingfaceof the guminer comes against the end flap, 00 with a layer of gumthereon which may be fully as thick or a little thicker than thethickness of the blank, and in case the gummer hasa .height greater thanthe vertical extension of the flap, 00 there will be a distance ofseparation,when the guinmer has come to its impact against theblank,between the face of the gummer and the proximate face of the bar,H, or the rabbeted part of the envelope, (1, therefor, greater than mayever be spanned by any layer of gum on the gummer. Thus there can be noaccumulating deposits of gum against the rear face of the impact-bar, H,to,

correspondingly properly brought to their due adjustments.

In order that, the aforesaid inturning device for the end-flap may haveits proper action against the fiap which, while being gummed andpreviously to beinginturned, lies against the inner side of the impactbar, H, faced as aforesaid, the said bar, H, is apertured as seen at 86.

The follower, G, has its descending movement,after the gummed flap, xand stay-sections, x have been inturned to set and unite these partsfirmlyrupon each other and toimpart the decided and true right-angularshaping to the end of the box by means, for instance, such as theduplicated cams, 88, which impinge forthe descent againstthe rollers,89, of the said follower and for the ascent of the follower against therollers, 90, which are carried at the upper ends of vertical arms,92.

Inaddition to the rests, B, B, projecting forwardly from the front ofthe bed of the machine there is also another stop or rest seen at L,which is below and between the said rests, being projected forwardlyfrom its supporting connection with theunder part of the bed so that thevertical face, 95, at its outer extremity will be substantially in aplane coincident with the outer vertical end faces, 21, of the saidrests.

This machine is so constructed and equipped that it may beintermittently given one complete operation at pleasure,-as occasionedby one complete rotation of its driving shaft,by means of the rod, 96,which may be actuated by a treadle, or otherwise, the endwise thrust ofwhich rod insures the establishment of clutched relations of the loosepulley, 97, on the main shaft, F, with the fixed collar, 98, on saidshaft through means of intervening devices which also automaticallysecure the unclutching when the one complete operation of the machinehas been effected, and which devices will be now pointed out.

The hub of the loose pulley, 97, has in circular arrangement a series ofsockets, 99, while the fixed collar, 98, has the bolt, 100, which playsin a socket, 102, therefor, in the said fixed collar, which is parallelwith the axis of said collar. This bolt, 100, carries the radial stud,103, which projects through and beyond the longitudinal slot, 10;,through the side of the collar which is open to the said socket, 102.The said radial stud, 103, of course revolves in consonance with'therotation of the shaft, F. Underthe shaft, F, and adjacent the path ofrevolution of said stud, 103, there is a bracket, or casting, 105, suit-ICC ably sustained by one of the uprights, a This part has at itsshelf-like top a construction such as seen in Fig. 12, that is, it has avertical slot, 106, the length of which is parallel with the shaft, F.At the forward side of the slot the bracket top is formed with anabutment, or raised wall, 107, which occupies a portion, only, of thelength of said slot while at the rear side of the bracket there isanother raised part, 108, with the rear surface thereof cam-formed, orbeveled, as seen at 109, the inclination of this bevel being from apoint at the rear of the bracket near its end which is toward the end ofthe shaft, F, to a point which is near the plane of the outer end of theabutment, 107. The angular lever, 72, to an arm, 110, of which theoperating rod, 96, is connected, has its other arm, 112, extended toplay within the aforesaid slot, 106, its extremity being between thestud, 103, and the end of the slot. Of course when the stud, 103, has aposition against the abutment, 107, which is when the bolt which carriesthis stud is withdrawn from its clutching engagement with the loosepulley, the collar, 98, and the shaft, F, as well, are restrainedagainst rotation. Now so soon as the angular lever, h, is swung to forcethe stud out from engagement with the abutment, 107, the bolt,100,ismoved into clutch,whereupon the main shaft, F, receives its rotarymovement, the now revolving stud, 103, being permitted to pass the end,113, of the abutment, 107. The plane in which this stud, 103, revolvesis one which intersects the oblique rearwardly presented face, 109, ofthe raised part, 108, so that one rotation of the shaft having beenalmost completed, the stud is, by its impingement against the camsurface, 109, caused to have a movement lateral to its plane ofrevolution, causing the bolt, 100, to be withdrawn from clutch and itsstud to assume a position to have its further progress impeded by theabutment, 107.

It will now be manifest from the foregoing description and a familiaritywith the accompanying drawings that this machine may be utilized asfollows: When the machine is at rest and the follower, G, is elevatedand the pusher, or inturning device, D, stands in its forward positionand the stay-section deflectors, O, are recededythe operative may, afterhaving seized the blank and bent the side flaps at right angles to thebottom, as shown in Fig. 10, slip the blank into the relative positionindicated in Fig. 6 so that the flap, d, at one end is pushed up andupon the inner face of the bar, H, the bottom section lies against theouter or front end faces of the rests, B, B, and the stop, L, the sideflaps, 00 lie against the opposite lateral sides of the rests, B, B, andbetween such sides and the supports, 0 0 while the stay sections, m mproject above the level of the tops of said rests. The machine is nowset in operation whereupon in their due times. the gummers, J, J, moveforwardly to gum the blank and recede, the

devices 0, O, inwardly deflect the stay sections and the pusher, D,inturns the end flap, whereupon the follower, G, descends and sets theinturned flap and stay sections, the devices, O', C, and D, and havingin good time, as determined by the grade of their operating cams,receded. The machine is now antomatically stopped by the unclutchingdevice whereupon the box is reversed and its other end is operated uponby the means, and in the manner described whereupon the completed box iswithdrawn to leave the machine clear for a repetition of the saidoperations.
